MONTANA COOLING APPARATUS Application led December 21, 1931. Serial No. 582,478. i

My invention relates to a dual refrigerating or cooling apparatus, the purpose of` which is to simultaneously lower the temperature of rooms in a building and to cool vegetables, cream, butter and any other perishable articles. A single apparatus accomplishes both purposes, the main device comprising a chamber in which an airblown continuous spray of water is used, said chamber including a container for food stuffs, etc.,

and accessible without exposure to the cooling means.

Further advantages and the use of my article are hereinafter fully set forth, reference being had to the accompanying drawing, in

which f Fig. 1 is a top or plan view of my cooling apparatus with small parts of the main cover broken out to expose certain details.

Fig. 2 is a longitudinal sectional elevation about as on line 2-2 in Fig. 1.

Fig. 3 is a detail view of an air outlet with iiexible positioning means to direct cool air from the apparatus into Va room at any de-` sired angle.

Referring to the drawing by reference numerals, 5 designates an elongated main compartment or housing shown as Aof box-like proportions and having a water-tight cover 6. At one end is an opening in which is fixed a tube 7 leading from a centrifugal blower 8 rotated by a suitable electric motor 9 of the kind adapted to be run at various selective speeds. Intermediate the blower and the casing 5 a water intake pipe 10 is connected at 11, said pipe having suitable water flow regulating means such as the valve 12.

The current of air generated by the fan is forced through pipe 7 toward the casing,

water from pipe 10 mixing in said air current and is sprayed into the casing with any required force.

Within the casing is a triangular compartment 13, the apex of which is in proximity to the inlet of pipe 7, the angular sides of the compartment being in the path of the forced spray which cools the walls of the compartment. Said compartment is a water tight container for vegetables, fruits,'preserves,vetc., an opening being provided inthe cover and vwhich is normally closed by suitable means such as the hinged lid 13 G.

Each side ofthe triangular compartment I provide a row of parallel deflectors 14-15 of which alternate ones 14 are xed to and ex- 55 tend angularly from the sides of the said compartment and the other ones 15 are fixed to the inner sides of the side walls of the main casing. The deiiectors nearest the intake end of the casing are comparatively low and the others relatively higher toward the rear of the casing. vThe outer deiectors terminate in spaced relation to the food compartmentv and the inner deflectors terminate in spacedl relation to the side walls for the purpose Of guiding the water cooled air'currents in a tortuous path as designated by arrows 16 to the rear part of the `main casing. 1 17 is an outlet pipe extending from the rearvend of the casing to one or more rooms of a house. g V The deflectors 14-15 are each preferably a curtain of any suitable moisture accumulat-y k ing material, each serving as a rigid wick partially immersed in a volume vof water 22 75 in the bottom of the casing and said volume remaining constant by simply providing an outlet or overflow pipe 23 at a desired height.

The deiiectors 14-15 Abeing of variable, stepped up heights it is obvious that all of so them will be contacted by the spray from intake 7 completely saturating the wicks,*and the latter will cool the volume of air passing over and between them as described.

Between the rearmost deflector, the walls of the casing and the exterior rear partsv of the container 13 is formed a comparatively large chamber C from which cooled air circulates through duct 17. The water spray orV particles projected from intake 7 is calculated 90 to be mostly settled by the time the Watercooled air reaches the said chamber and cooled but comparatively dry air enters the conducter pipe 17. Said pipe may lead to one or more terminal outlets of Which a preferred form is shown in Fig. 3. 18 is a Wall in which pipe 17 leads to a. flexible tube 19 conducting the cool air to a suitable outlet 2O Which may be directed as desired into a room to be cooled.

I have now full, Vdisclosed a preferred embodiment orp and t e use of my cooling apparatus. Y It is obvious that the contents of container 13 is Vaccessible only by raising lid 14. In Fig. 1, 21 kdesignates a screen or other foraminous fixed intake pipe cover for breaking up into line particles the Water passing therethrough. This part 21 may be used or omitted as may be desired.`

It Will non7 be readily understood that my device provides for a continuous supply oi'v Water cooled air in one or more rooms of a house, the air cooling means simultaneously cooling the container 13 to keep foodstuffs, etc., in desirable condition.

Modifications of structure may be embodied without departing Jfrom the scope and spirit of the invention.

A condition not hitherto described is that the combination Wick-vanes lit- 15 are at all times completely saturated, the capillary action of the partly immersed Wicks keeping them always moist in their areas exposed to the air current from pipe 7. The constant spray of cold Water further saturates Wicks and coo-ls the entire interior of the main chamber and provides the supply of cool air required as described.

l claim:

1. In a dual cooling apparatus of the class described including an elongated quadrangular main chamber with a forced air intake in one end and a cold airoutlet at the opposite end, a storage chamber Within said main chamber and provided With means for access through the top of the main chamber, and a liquid supply pipe connected to said air intake; said storage chamber of triangular form and fixed With its apex in proximity to said intake o'ic the main chamber, upright Wicks in said main chamber and fixed in parallel spaced relation, in tW-o groups, one group at each side of the storage chamber and extending from near the intake end of the main chamber toward the Wider and rear end ofthe storage chamber.

2. The structure speciiied in 'claim 1 in which each said group of Wickscomprises a series of members vextending' upward lfrom the bottom of the main receptacle, alternate Wicks lixed also to the inner side Wall parts of the main chamber and terminating in spaced relation to the storage chambenthe other Wicks of each group lixed toV the side Wallsof the storage chamber .and extending Josnrn A.
